Abstract (en)
[origin: WO2014060041A1] The invention refers to a mechanical coolant pump (10) for an internal combustion engine, comprising an impeller pump wheel (40) pumping the liquid coolant incoming in axial direction radially into an outlet volute (13), a pump housing (12) defining the outlet volute ( 13) and comprising an outlet valve arrangement fluidically being arranged between the outlet volute (13) and the pump outlet (14) for closing or opening a valve opening (15). The outlet valve arrangement comprises a pivotable valve body (20) comprising a closing element (22) for directly covering the valve opening (15) provided with an opening seat ( 19) in the closed valve position. The valve body (20) comprises two parallel end disks (28,32) at both axial ends of the closing element (22), the end disks (28,32) being arranged perpendicular to the closing element (22) and being rotatable around a pivot axis (30) perpendicular to the end disks (28,32). Both end disks (28,32) are provided with a radial clamping nose (70,70') acting together with a corresponding support portion (71,71') of the pump housing (12) to radially push the closing element (22) against the valve opening seat (19) in the closed valve position, only.
